Specification of Letters Patent.

.Application led May 28, 1 908.A Serial No. 435,474.

To all whom t may concern.'l

Be it known that I, CARL A. GEHNE, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Nail-Setters; and I dodeclare the following to be a full, clear', and exact descriptionof theinventiomsuch as willenable others skilled in the 1art to which' itappertains to make and use the same.

My invention relates to nail driving and setting devices. f

The object of the invention is to provide a device ofthis characterwhich may be ad` justed for different size brads or nails and which maybe used in an inverted position equally as well as in anvuprightposition.

With these and other objects in view, the invention consists of certainnovel features of construction, 'combination and arrangement of parts,as will be more fully described and particularly pointed out in theappended claim.

vIn the drawings, Figure 1 is a side eleva- 'tion of the device withparts broken away,

showing the nail in the act of being driven ;`l

. Fig. 2. is a side elevation showing thenail completely driven;-Fig. 3is a longitudinal section of the device; an.d\1*`ig. 4 is a transverseAsectional view taken on the line 4 4 of Fig. 1. o 4Referring moreespecially tothe drawings, 1 represents a' tubular body which isinternally-threaded at 2 and 3 to receive the nail cap 4 and thelimiting cap 5 as is shown in Fig. Slidably mounted in the tubular bodyand extending through the limiting capv5 is a plunger 6 having its rearend re duced so as to form a shoulder 7 adapted to engage with theshoulder 8 produced by the cap 5 entering'the tube 1 so as to limit therearward movement of the plunger. ,-The forward part.' of the plunger 6is provided -with a greatly reduced operating end 9 which isadapted toengage theheads of the nails for driving and force them to their seat.

In the foremost position of the plunger the drivingv extension 9 has itse'nd project slightly 'beyond the nail cap 4. The

shoulder 10 is formed by the. reduction of the' plunger to produce thenai-l drivingend 9 at the inner end of the tube and limits forwardmovement of the plunger.

In order to hold the plunger in striking position for setting nails inwork overhead I providea thumb piece 11 which is provided the withoutwardly beveled edges 12 adapted to engage the beveled edges 13 of thetubular Y member 1. This construction allows free inward movement of thethumb piece 11 but.

prevents outward movement beyond 'the periphery of the tube. i

In using a device for driving nails the plunger is retracted to its fullextent and the f brad or nail placed in the opening 14, which passesthrough the nail cap 4, against the 'l 'lar body 1 and the point of thedriving eX- tension 9 placed upon the head of the nail. The nail cap 4is then forcibly held down upon the body in which the nail is seated.lThe outward end of the plunger is then forced down to the shoulder 10or inner end ofthe nail cap 4, this limits the movement thereof andgives the required set to each nail. In using a device. for settingnails overhead the plunger is, rst pushed up'- wardly to its limit andthe thumb piece 11 forced in against the plunger so as to prevent itdropping back by gravity, the device is then used as formerly described,as for setting or driving nails.

By changing the plunger and the nail cap 4 I may provide a device whichis capable of driving and setting dilferent size brads or nai s..

From the foregoing description, takeny in connection with theaccompanyin drawings, the construction and operation 0 the inventionwill be readily understood without re'- quiring a more extendedl exlanation.

`Various changes in the orm, proportlon and the minor details ofconstruction may be resorted to without departing from the prin,

nature o my invention, what I claim as new and desire to secure byLetters-Patent, is

A' nail driving and setting device comprising a ltubular body, achanneled guiding memberin one endlthereof, a lunger having a drivingextension-longer t an the guide member, said lunger slidably mounted inthe tubular bo' y wlth the driving extension appended und a loosely'mounted plate adapted to be manipulated by the operator tofrlctionallyv enga ge the'plunger to hold its extension projected beyondthe' end of the guiding member whereby the device may be used 1n aninverted position for setting nails and the guiding device Will limitthe set of thevnail..

In testimony whereof I have hereunto set my hand 1n presence of twosubscribing Wlt- 10 nesses. l
